Severity: Normal Title: Ghostscript: User-assisted execution of arbitrary code Date: March 23, 2009 Bugs: #261087 ID: 200903-37

Synopsis ========
Multiple integer overflows in the Ghostscript ICC library might allow for user-assisted execution of arbitrary code.
Background ==========
Ghostscript is an interpreter for the PostScript language and the Portable Document Format (PDF).
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/ghostscript-gpl < 8.64-r2 >=3D 8.64-r2 2 app-text/ghostscript-gnu < 8.62.0 >=3D 8.62.0 3 app-text/ghostscript-esp <=3D 8.15.4-r1 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
Jan Lieskovsky from the Red Hat Security Response Team discovered the following vulnerabilities in Ghostscript's ICC Library:
* Multiple integer overflows (CVE-2009-0583).
* Multiple insufficient bounds checks on certain variable sizes (CVE-2009-0584).
Impact ======
A remote attacker could entice a user to open a specially crafted PostScript file containing images and a malicious ICC profile, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GPL Ghostscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dapp-text/ghostscript-gpl-8.64-r2= "
All GNU Ghostscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dapp-text/ghostscript-gnu-8.62.0"=
We recommend that users unmerge ESP Ghostscript and use GPL or GNU Ghostscript instead:
# emerge --unmerge "app-text/ghostscript-esp"
For installation instructions, see above.
